to see the effects of all accesses prior to the beginning of that grace

Similarly, any code that happens before the beginning of a given RCU grace
period is guaranteed to see the effects of all accesses following the end
period is guaranteed to not see the effects of all accesses following the end
of that grace period that are within RCU read-side critical sections.
